Referring to fig. 1 and 2, the tube cutter comprises a blade carrier, a blade 140 and a guide wheel 130. The tool rest is of an O-shaped structure, and comprises a first supporting part 110 and a second supporting part 120 which are of arc-shaped plate structures. And, the concave sides of the first and second supporting

parts

110 and 120 are disposed to face each other. The guide wheel 130 is rotatably connected to the middle portion of the first supporting portion 110, and the axis is perpendicular to the plane of the first supporting portion 110. The blade 140 is a circular ring structure, the blade 140 is rotatably connected to the middle portion of the second supporting portion 120, and the axis is perpendicular to the plane of the second supporting portion 120. The tool post can be sleeved on the pipe to be cut so that the edges of the guide wheel 130 and the blade 140 are abutted against the outer side wall of the pipe to be cut. Specifically, the tool rest is sleeved on the pipe to be cut, so that the tool rest rotates around the axis of the pipe to be cut. In the process, the guide wheel 130 can guide the rotation direction of the tool holder, and the blade 140 can cut the pipe. After the tool rest rotates 360 degrees, the pipe is cut off to form a cut. Therefore, the restriction of the space to the cutting operation is greatly reduced, and the operation is simple and convenient.

In this embodiment, one end of the first support portion 110 and the other end of the second support portion 120 are connected. And, the minimum distance between the first and second supporting

parts

110 and 120 is adjustable. It should be noted here that the minimum distance refers to a distance between the middle portion of the first support portion 110 and the middle portion of the second support portion 120. By adjusting the minimum distance between the first supporting portion 110 and the second supporting portion 120, the tool holder can be sleeved on the pipes with different calibers to cut the pipes with different calibers, that is, the pipe cutter is not limited by the calibers of the pipes any more, and the universality of the pipe cutter is effectively improved.

In an embodiment of the present invention, the first adjusting lever 150 and the second adjusting lever 160 are further included. One end portions of the first supporting portion 110 and the second supporting portion 120 are respectively provided with a first mounting hole 121, and one end portions of the first supporting portion 110 and the second supporting portion 120 are fixedly connected through the first mounting hole 121 by using a first adjusting rod 150. The other ends of the first and

second support portions

110 and 120 are opened with second mounting holes 122, and the other ends of the first and

second support portions

110 and 120 are fixedly connected by second adjustment rods 160 through the second mounting holes 122. The first mounting hole 121 and the second mounting hole 122 are through holes.
